Kibana refresh is failing

Hi,
I am pushing the logs to elasticsearch and read them through kibana.
when I use localhost:5601 it is giving 15 min search query data.
When I refresh this, it says "no results found".
Can someone hava a look and let me know.

Regards
ESUser,

We need more information.

Have you set the index setting to the right Elasticsearch index? Are you sure there is data there?

hi, I tried to change the data type of some of the fields. In doing so I stuck up with the issue.

Then you need to refresh the cached mappings for the index, you can do that in the Settings for the index.
